If you want to keep them, yes you do, mIRC Destroys hash tables when it closed/exits...

if you want to save a hash table:
Code:
on *:exit:{
if ($hget(christest)) { hsave -o christest christest }
}

That will save -o(Overide Existing file) Table name(christest), To File name(christest)


If you want to load a file:

Code:
on *:start:{
hmake christest 10
hload christest christest
}


that will make the table(Christest) at a size of 10(plenty for what your doing)
then it will load the table(christest) from the file christest
